Reduce water bills, lower mains water consumption, and make your home more environmentally friendly with the Klargester AquaHarvest 4600L Direct Rainwater Harvesting System. Designed specifically for domestic properties, this advanced rainwater harvesting system captures, stores and reuses rainwater for a range of everyday non-potable applications, helping homeowners maximise water efficiency without compromising performance.

The AquaHarvest Direct System is the ideal solution for homes where a traditional header tank is not practical, such as properties with converted loft spaces or limited attic storage. Instead of relying on gravity-fed distribution, the system uses an intelligent Grundfos pressure pump to deliver filtered rainwater directly from the underground storage tank to appliances at mains pressure or higher.

 

Why Choose the Klargester AquaHarvest 4600L?

With a generous 4,600-litre capacity, the AquaHarvest provides an efficient and sustainable way to reduce reliance on mains water. By harvesting naturally occurring rainfall, homeowners can significantly cut annual water usage while reducing their environmental impact.

The system is fully compliant with EN 16941-1:2018 Rainwater Harvesting Standards, providing complete peace of mind that your installation meets the latest industry requirements.

 

Key Features & Benefits

  • 4,600 litre underground rainwater harvesting tank
  • Direct-feed system with no header tank required
  • Ideal for homes with converted lofts or limited roof space
  • Fully compliant with EN 16941-1:2018
  • Intelligent Grundfos pump for reliable performance
  • Supplies water at mains pressure or higher
  • Suitable for shallow excavation installations
  • Easy-to-use control panel with water level monitoring
  • Early fault warning and system status indicators
  • Automatic mains water backup during dry periods
  • Calmed inlet design helps maintain optimum water quality

Suitable Uses for Harvested Rainwater

The AquaHarvest system supplies filtered rainwater for a variety of domestic applications, including:

  • Toilet and WC flushing
  • Urinal flushing
  • Garden watering
  • Irrigation and landscaping
  • Vehicle washing
  • Domestic laundry

By using harvested rainwater instead of treated mains water for these applications, households can make substantial savings over time.

 

Save Water, Save Money

A typical four-bedroom home uses approximately 222 litres of water every day, with around 30% used for toilet flushing and a further 7% used outdoors. By replacing mains water with harvested rainwater for these non-potable uses, the Klargester AquaHarvest 4600L can help save up to 30,000 litres of mains water per year, helping to reduce household water bills while conserving valuable resources.

 

How the AquaHarvest Rainwater Harvesting System Works

Rainwater collected from the roof is channelled into the AquaHarvest system where it undergoes multiple stages of filtration before use:

  1. Rainwater passes through an inline leaf filter to remove larger debris.
  2. Additional filtration is provided at the pump inlet.
  3. Fine filtration ensures clean water delivery throughout the system.
  4. The intelligent Grundfos pump automatically activates whenever water demand is detected.
  5. During prolonged dry weather, an automatic mains water top-up prevents the system from running dry.

The result is a reliable, fully automated rainwater recycling system that delivers water efficiently whenever it's needed.

 

Ideal For

  • New build homes
  • Self-build projects
  • Eco-friendly housing developments
  • Sustainable residential properties
  • Homes seeking to reduce water bills and environmental impact

 

The Klargester AquaHarvest Domestic 4600L Direct Rainwater Harvesting System combines innovative pump technology, advanced filtration and dependable performance to provide a highly efficient solution for domestic rainwater reuse, helping homeowners save water, save money and support a more sustainable future.
